From 1a22bc7aeabcd8a2a5828b3d0391896d19d74378 Mon Sep 17 00:00:00 2001 From: mohammed ahmed Date: Mon, 6 Apr 2026 10:49:28 +0000 Subject: [PATCH 1/2] Fix Jest globalSetup/globalTeardown causing Docker dependency failures **Problem:** Codeflash was failing to run tests for projects that use Jest globalSetup or globalTeardown hooks with external dependencies (e.g., Docker, testcontainers). When these hooks failed, all optimization attempts were blocked. **Root Cause:** Three config generation functions were extending original Jest configs but not disabling globalSetup/globalTeardown hooks, causing inherited dependencies to fail: - _create_codeflash_jest_config - _create_runtime_jest_config - _get_jest_config_for_project (only created configs for bundler moduleResolution) **Solution:** 1. All generated Jest configs now explicitly set: - globalSetup: undefined - globalTeardown: undefined 2. _get_jest_config_for_project now ALWAYS creates a codeflash config (not just for bundler moduleResolution projects) 3. Added check to skip requiring TypeScript configs (jest.config.ts) which cannot be parsed by CommonJS require() **Testing:** - Added 6 new unit tests covering all config generation scenarios - All 69 existing JavaScript tests pass - Verified fix eliminates Docker/globalSetup errors in Budibase optimization runs **Impact:** Codeflash-generated tests are now self-contained and don't trigger project-level global setup/teardown hooks, making optimization work on more projects.
